These nuts are provided to take up any slack or play that may develop between the rod and the hangers. These hangers are fastened to the underside of the base flange l8 and have stop fingers 3| directed toward the cradle and in the path of the arms l9. These hangers may be positioned at any desired points on the beam and are sufliciently spaced apart to permit the plunger 28 to travel any predetermined distance within the length of the cylinder. It is obvious that movement of the plunger in the cylinder will contribute longitu dinal movement to the beams.

A hand pump 32 is mounted on, an extension A suitable packing 56 surrounds the plunger at.

the top of the barrel forpreventing fluid leaking out of said barrel by the plunger. An ordinary four way controlling valve 34 is connected to the pump and preferably mounted thereon, as is shown in Figures 1, 2, 3 and 5. The valve is provided with the usual rotor 35, having cut out portions 36. Inlet duct- 31 and outlet duct 38 are diametrically opposite each other in the valve and are connected to the pump. Ports 39 and 40 are positioned diametrically opposite each other and open into nipples 4| and42. g

The ends of the cylinder are connected to the valve by pipes 43 and '44 extending therefrom and engaging in the nipples 4| and 42 respectively. The valve is equipped th an operating handle 45 having a pointer thereon, and an indieating dial 46 for showing in which direction the fluid may flow, when it is pumped. 'Thus, it will be seen that by turning the. rotor'35 the flow of the fluid is controlled, so that the fluid may either be pumped from one end of the cylinder to the other, and vice versa, or it is prevented from flowing at all by the rotor closing the ports 39 and 40.

It will be seen that by operating the valve rotor, the beam may be adjusted in either direction or stopped by closing the ports 39 and 40. Thus, by working the valve rotor back'and forth, finer and more minute adjustments of the beam may be obtained.

The operation is as follows: When it is desired to longitudinally adjust the walking beam, the keepers 22 are loosened and; the valve operating handle 45 is turned to the proper position. The lever 41 is swung and the fluid is pumped, according to the way the rotor 35 has been set, from one end of the cylinder to the other.' The fluid is pumped between the plunger 28 and the end of the cylinder 23 and forces the plunger toward the other end. The beam l8, being connected to the plunger by the plunger rod 26 and the hangers 29, will move longitudinally whenever the plunger is moved.

When it is required to move the walking beam to the right, (Figure 1) the valve is adjusted so that the rotor is in the position shown, in Figure 7. The pipe 43 and port 39 will be connected to the outlet duct 38 and the pipe 44 and port 40 will be connected to the inlet duct31. The pump is now operated and the fluid is drawn'from the rlght-handend of the cylinder through the pipe 44 and port 40 and intothepump through the inlet duct 31. The fluid is expelled from thepump through the outlet duct 38, then through the port 39 and pipe 43, into the left-hand end of the cylinder. The fluid will force the plunger to the right and also, the beam which is connected to the plunger. Thus, it will be seen that the beam can be moved as far to the right as is necessary. The keepers are now tightened and the beam will be clamped in its shifted position.

To limit travel of the beam I8 and the plunger 28, the stop fingers 31 on the hangers 29 engage the ends of the arms I9 of the cradle l2 and thus, the plunger is prevented from becoming jammed in the ends of the cylinder.

When it is desired to move the beam to the left, the rotor is rotated to the position shown, in Figure 6. In this position, the pipe 43 is connected to the inlet duct 31 and the pipe 44 is connected to the outlet duct 38. The rest of the operation is the same. The plunger and beam are 1.
